Study design: Retrospective case note review. Objectives: To review the results of metallic urethral stents used in patients with neuropathic bladder dysfunction after spinal cord injury (SCI). Setting: Rehabilitation unit for SCI and stroke, Cape Town, South Africa. Methods: We performed a case note review of dual flange Memokath™ stents placed from March 2008 until October 2011. Stents were placed rather than performing an external sphincterotomy in selected patients. With the patient under deep general anaesthesia, a thermo-sensitive expandable metallic stent was positioned over the internal and external urethral sphincters. Results: In total, 33 stents were placed in 28 male patients. SCI was cervical in 23 patients and thoracic in 5. Average follow-up was 18 months (range 1-40 months, median 18 months). The most common indications were repeated catheter blockage in 8 patients and urinary tract infection in 6. The average time from SCI to stent insertion was 79 months (range 1 - 468, median 21 months). Severe autonomic dysreflexia was present in 17 cases prior to stenting and in 7 after stents were placed (p=0.003). Stents failed in 15 patients (45%) and were removed. The most common reason for failure was stone formation. Comparing the group of patients with stents lasting >20 months (n = 11) to the group with stent removal before 20 months (n = 10), the mean time between SCI and stent placement was 31 vs. 119 months (p = 0.057). Medium term results (up to 27 months) were significantly influenced by earlier stent placement (p = 0.0484). One major complication was stent migration that caused an urethro-cutaneous fistula. |
